Overbite depth와 하악과두 위치에 관한 연구
조원표 건국대학교 의과학연구소 1995 건국의과학학술지 Vol.5 No.-
This study was designed to evaluate the relationship of mandibular condylar position to overbite depth and compare the findings from transcranial radiographs and those from indivisualized corrected tomographs in determination of condylar position. The subjects consisted of 20 control subjects(male 8, female 12), and 23 deep-bite patients(male 17, female 6). The mean age was 23.6 years for the control group, and 23.2 years for deep-bite group. Transcranial radiographys and individualized corrected tomographys in centric occlusion were taken from right and left temporomandibular joints of each subject. The results were as follows. In the 20 normal subjects showing no symptoms of TM disorder, the incidence of condylar retrusion was 27.5%, middle condylar position 60.0%, and anterior displacement 12.5%. Only 45.2% of the findings from transcranial radiographs coincided with those from individualized corrected tomographs in determining condylar position. There was significant correlation between the bite depth and observed condylar position.

A 62-year-old man with progressive swelling on his left thigh and leg was referred to the Division of Vascular Surgery. Anticoagulation therapy did not prevent or improve the symptoms of chronic deep vein thrombosis (DVT) from his left external iliac vein to posterior tibial vein. He had no trauma history nor any accidents. He underwent femoral endovenectomy, thrombectomy and stent insertion in left iliac vein. The patient had additional balloon angioplasty for stenosis in left common femoral vein. He had an uneventful postoperative recovery without complication. Leg swelling has been improving and follow-up continues under anticoagulation. We report a case of femoral endovenectomy with iliac stenting, which may be an efficacious treatment for chronic DVT.

Purpose: Endovascular treatment for peripheral arterial obstructive disease (PAOD) is replacing traditional arterial bypass in the western world. Yet there are few reports to evaluate the pattern of clinical practice pattern for PAOD in Korea. This study was conducted to evaluate the treatment pattern for PAOD between endovascular treatment and arterial bypass, and to compare their clinical characteristics. Methods: We conducted a retrospective study on the prospectively maintained database of patients who underwent endovascular treatment and arterial bypass for PAOD from March 2005 to December 2009 in Inha University Hospital. The aortoiliac lesions and femoropopliteal lesions were categorized by the Trans Atlantic Inter-Society Consensus (TASC) II classifications. Their treatments and clinical characteristics were compared between the former period (2005∼2007 y) and the latter period (2008∼2009 y). Results: Three hundred nine cases (178 patients) were treated for PAOD by either arterial bypass or endovascular treatment. The patients’ mean age was 69.1±11.3 year old. There was no difference in clinical characteristics between the two periods except for age. Endovascular treatments of both aortoiliac and femoropopliteal arterial lesions were increased in the latter period (P=0.023, P<0.001). Also, the endovascular treatments were increased in the TASC C and D aortoiliac and femoropopliteal lesions in the latter period (P=0.020, P<0.001). Conclusion: Endovascular treatment for PAOD is increasing in clinical practice and this shows feasibility in critically ill patient with TASC C and D lesions, although arterial bypass is still important.
악관절 장애환자의 교합 안정장치 사용 전후의 적외선 체열영상에 관한 연구
조원표 건국대학교 의과학연구소 1998 건국의과학학술지 Vol.8 No.-
Thermography is a sensitive and reliable method for diagnosis of temporomandibular joint disorder. Digital infrared thermographic imaging system is noninvasive, easy to reading, objective and physiologic instrument by measuring and imaging infrared energy emitted from skin surface. Computerzed digital infrared thermographic imaging is comfortable method for diagnosis of disease and evaluation for treatment result. The author presents the result of digital infrared thermographic images of 36 patients of temporomandibular disorder. The author has done digital infrared thermographic imaging preconservative and postconservative treatment. In digital infrared thermographic imaging before use of occlusal stabilization splint, the diagnostic sensitivity is about 83.3%. In digital infrared thermographic imaging after use of occlusal stabilization splint, the result is about 73.3%.

The lateral soil movement in soft grounds undergoing improvement with application of vertical drains is analyzed on the basis of monitoring data at three fields, in which fifty six monitoring sites are located. Based on the investigations, the criterions are suggested to predict the lateral soil movement. In order to predict the lateral soil movement in the improved soft grounds by using the dimensionless parameter R suggested by Marche & Chapuis (1974), it is desirable that the maximum lateral displacement in the soft ground below the toe of embankment should be applied to calculate R instead of the lateral displacement at the toe of embankment. The lateral soil movement may increase rapidly, if the safety factor of slope is less than 1.4 in case of high ratio of H/B (Thickness of soft ground/Embankment width) such as 1.15 or is less than 1.2 in case of low ratio of H/B such as 0.05. Also, the graph suggested by Tschebotarioff (1973), which illustrates the relationship between the maximum height of embankments and the undrained shear strength of soft grounds, can be applied to the evaluation for the possibility of the lateral soil movement due to embankments on soft grounds.
顎矯正術을 받은 顎顔面 寄形患者의 SKELETAL PATTERN의 變化에 關한 硏究

In the treatment of dentofacial deformities, analysis of skeletal pattern, with evaluation of plaster dental case, is essential procedure. This study was based on 20 patients with dentofacial deformity who were admitted to the department of oral and maxillofacial surgery Kngnam sacred heart Hospital during the period of Jan 1989. We studied serial cephalometric radiogarphs of patients (pre-op, postop immediately, postop 6 moth). The obtained results indicates the good resistance of rigid fixation against relapse in orthognathic surgery.
